Associations between facial expressions and observational pain in residents with dementia and chronic pain.

AIM: To identify specific facial expressions associated with pain behaviors using the PainChek application in residents with dementia. DESIGN: This is a secondary analysis from a study exploring the feasibility of PainChek to evaluate the effectiveness of a social robot (PARO) intervention on pain for residents with dementia from June to November 2021. METHODS: Participants experienced PARO individually five days per week for 15 min (once or twice) per day for three consecutive weeks. The PainChek app assessed each resident's pain levels before and after each session. The association between nine facial expressions and the adjusted PainChek scores was analyzed using a linear mixed model. RESULTS: A total of 1820 assessments were completed with 46 residents. Six facial expressions were significantly associated with a higher adjusted PainChek score. Horizontal mouth stretch showed the strongest association with the score, followed by brow lowering parting lips, wrinkling of the nose, raising of the upper lip and closing eyes. However, the presence of cheek raising, tightening of eyelids and pulling at the corner lip were not significantly associated with the score. Limitations of using the PainChek app were identified. CONCLUSION: Six specific facial expressions were associated with observational pain scores in residents with dementia. Results indicate that automated real-time facial analysis is a promising approach to assessing pain in people with dementia. However, it requires further validation by human observers before it can be used for decision-making in clinical practice. IMPACT: Pain is common in people with dementia, while assessing pain is challenging in this group. This study generated new evidence of facial expressions of pain in residents with dementia. Results will inform the development of valid artificial intelligence-based algorithms that will support healthcare professionals in identifying pain in people with dementia in clinical situations. REPORTING METHOD: The study adheres to the CONSORT reporting guidelines. PATIENT OR PUBLIC CONTRIBUTION: One resident with dementia and two family members of people with dementia were consulted and involved in the study design, where they provided advice on the protocol, information sheets and consent forms, and offered valuable insights to ensure research quality and relevance. TRIAL REGISTRATION: Australian and New Zealand Clinical Trials Registry number (ACTRN12621000837820).

Nurses' Beliefs About Pain Assessment in Dementia: A Qualitative Study Informed by the Theory of Planned Behaviour.

AIM: To explore registered nurses' beliefs regarding pain assessment in people living with dementia. DESIGN: A descriptive exploratory qualitative study informed by the Theory of Planned Behaviour. METHODS: Online semi-structured in-depth interviews were conducted from January to April 2023 with a purposive sample of 15 registered nurses caring for people with dementia. Following transcription, data were analysed using direct content analysis. FINDINGS: Registered nurses believe pain assessment improves the well-being of people with dementia and informs and evaluates practice. However, there is a possibility of misdiagnosing pain as agitation or behavioural problems, leading to inaccurate pain management. Interpersonal factors, such as registered nurses' knowledge and experience, beliefs and motivation to improve care provision, were the primary facilitators of pain assessment. Physical and behavioural dimensions of the pain of the dementia syndrome were the most reported barriers to pain assessment. Registered nurses reported that multidisciplinary team members expect them to do pain assessments. Most did not experience disapproval when performing pain assessments. CONCLUSION: Registered nurses hold beliefs about pain assessment benefits, consequences, enablers, barriers, approvals and disapprovals regarding dementia. The findings could inform interventions to enhance pain assessment practices. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Policymakers should provide education opportunities for registered nurses to improve their knowledge, skills and beliefs about pain assessment in dementia. Future research should develop and implement multidisciplinary, multifaceted pain assessment protocols to enhance the accuracy of pain assessment practices. IMPACT: Pain is underassessed in dementia, and this could stem from registered nurses' beliefs about pain assessment in dementia. The findings could inform interventions to enhance pain assessment beliefs and practices. REPORTING METHOD: This study adhered to the COREQ criteria. PATIENT OR PUBLIC CONTRIBUTION: Registered nurses caring for people living with dementia participated as interview respondents.

Factors related to nurses' beliefs regarding pain assessment in people living with dementia.

AIM: To evaluate registered nurses' beliefs and related factors regarding pain assessment in people living with dementia. DESIGN: A descriptive cross-sectional survey was conducted between July 2022 and April 2023. METHODS: An online survey comprised of demographics, knowledge scale, and beliefs scale relating to pain assessment in dementia was distributed to registered nurses (RNs) caring for people living with dementia in Australia. RESULTS: RNs (N = 131) completed the survey. Most respondents were females (87.0%) and self-identified as Caucasian (60.3%). The mean beliefs score was 72.60 (±6.39) out of a maximum possible score of 95. RNs' beliefs about pain assessment varied based on their education, dementia pain assessment knowledge, nursing experience, and ethnicity. Hierarchical multiple regression analysis revealed factors significantly related to the beliefs score (i.e. education and dementia pain assessment knowledge). CONCLUSION: The relationship between education and knowledge, and the beliefs score indicates the potential to improve RNs' knowledge and overcome their erroneous beliefs about pain assessment in dementia. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Education and training in assessing pain in people living with dementia should be tailored to overcome RNs' misconceived beliefs. These programmes should be integrated into continuous learning programmes. IMPACT: Some RNs' beliefs about pain assessment in dementia were not evidence-based, and knowledge and educational status were the strongest factors related to RNs' beliefs. RNs' erroneous beliefs about pain assessment in dementia need to be addressed to improve pain assessment and management. Researchers should explore the potential of educational interventions to overcome RNs' misconceived beliefs about pain assessment in dementia. REPORTING METHOD: This study was reported adhering to the Strengthening the Reporting of Observational Studies in Epidemiology checklist. PATIENT OR PUBLIC CONTRIBUTION: RNs caring for people living with dementia participated as survey respondents. Additionally, RNs were involved in the pre-testing of the study's survey instrument.

A meta-analysis of person-centered care interventions for improving health outcomes in persons living with dementia.

BACKGROUND: Person-centered care emphasizes the importance of valuing and supporting the humanness of a person living with dementia as compared to focusing heavily on disease symptom management and treatment. The state of the evidence and outcomes from person-centered care is unclear and is an important knowledge gap to address informed evidence-based care for persons living with dementia. AIMS: To synthesize the evidence on the efficacy of person-centered care in improving health outcomes in people living with dementia. METHODS: Our search using the following databases: Academic Search Complete, CINAHL, COCHRANE library, EMBASE, MEDLINE, PubMed, and Google Scholar. The methodology quality of the included studies was assessed using a revised Cochrane risk-of-bias tool for randomized trials. Meta-analyses were performed using the DerSimonian and Laird random effects model to investigate the effectiveness of person-centered care on improving health outcomes in persons living with dementia. RESULTS: Seventeen trials were included in this systematic review and meta-analysis. Person-centered care implementation was found to improve cognitive function (pooled SMD: 0.22; 9CRD420223808975% CI [0.04, 0.41], p = .02) in persons living with dementia, although outcomes including the impact of the care model on activities of daily living, agitation, depression, and quality of life remain inconclusive. LINKING EVIDENCE TO ACTION: Person-centered care improves the cognitive function of persons living with dementia, which is clinically meaningful and should not be ignored or overlooked in delivering evidence-based care to this population. The findings of this study emphasize the importance of person-centered care implementation among people living with dementia as an approach in improving health outcomes particularly on cognitive function improvement. Person-centered care emphasizes the personhood of individuals living with dementia while respecting their needs, values, and beliefs and is identified as a preferred model of delivering dementia care in all settings as a non-pharmacological approach.

Clinical characteristics of peripherally inserted central catheter-related complications in cancer patients undergoing chemotherapy: a prospective and observational study.

PURPOSE: The incidence of peripherally inserted central catheter (PICC)-related complications is higher in cancer patients than in noncancer patients. However, the pattern of specific complication occurrence over time remains unclear. The purpose of this study was to investigate the clinical characteristics of PICC-related complications in cancer patients undergoing chemotherapy. METHODS: This prospective, observational study was conducted at a university-affiliated hospital in Western China. Cancer patients undergoing PICC insertion for anticancer treatment were recruited and followed up until the first week after catheter removal. Any complications, including occurrence time and outcomes, were recorded. The trajectory of specific PICC-related complications over time were identify based on the Kaplan‒Meier curve analysis. RESULTS: Of the 233 patients analyzed, nearly half (n = 112/233, 48.1%) developed 150 PICC-related complication events. The most common were symptomatic catheter-related thrombosis (CRT) (n = 37/233, 15.9%), medical adhesive-related skin injury (MARSI) (n = 27/233, 11.6%), and catheter dislodgement (n = 17/233, 7.3%), accounting for 54.0% (n = 81/150, 54.0%) of total complications events. According to Kaplan‒Meier curve analysis, symptomatic CRT, pain, phlebitis, and insertion site bleeding were classified as the "early onset" group mainly occurring within the first month post-insertion. Catheter fracture and catheter-related bloodstream infection were classified as the "late onset" group occurring after the second month post-insertion. MARSI, catheter dislodgement, occlusion, and insertion site infection were classified as the "persistent onset" group persistently occurring during the whole catheter-dwelling period. Among the 112 patients with PICC-related complications, 50 (44.6%) patients had their catheters removed due to complications, and 62 (55.4%) patients successfully retained their catheters until treatment completion through conventional interventions. The major reasons for unplanned catheter removal were catheter dislodgement (n = 12/233, 5.2%), symptomatic CRT (n = 10/233, 4.3%), and MARSI (n = 7/233, 3.0%), accounting for 58.0% (n = 29/50, 58.0%) of the total unplanned catheter removal cases. Catheter dwelling times between patients with complications under successful interventions (130.5 ± 32.1 days) and patients with no complications (138.2 ± 46.4 days) were not significantly different (t = 1.306, p = 0.194; log-rank test = 2.610, p = 0.106). CONCLUSIONS: PICC-related complications were pretty common in cancer patients undergoing chemotherapy. The time distribution of PICC-related complications varied, and medical staff should develop time-specific protocols for prevention. Because more than half of the patients with PICC-related complications could be managed with conventional interventions, PICCs remain a priority for cancer patients undergoing short-term chemotherapy. The study was registered in 02/08/2019 at Chinese Clinical Trial Registry (registration number: ChiCTR1900024890).

Status and associated factors of gerontological nurse specialists' core competency: a national cross-sectional study.

BACKGROUND: Nurses' core competency directly affects patients' safety and health outcomes. Gerontological nurse specialists play an essential role in improving older adults' health status. However, little is known about their core competency level and the factors influencing core competency. Therefore, this study aimed to investigate the status of core competency and factors influencing the core competency of gerontological nurse specialists in China. METHODS: A multicenter cross-sectional study was conducted on gerontological nurse specialists certified by province-level or above organizations across China between March 2019 and January 2020. The Revised Core Competency Evaluation Instrument for Gerontological Nurse Specialists was used to measure participants' core competency. The median, frequencies, and percentages were used to describe participants' characteristics and level of core competency. Multivariate stepwise regression analysis was applied to analyze the factors influencing core competency. RESULTS: The median score of gerontological nurse specialists' core competency was 3.84, and professional development skills and research and analysis decision-making skills had the lowest scores among the dimensions. The multivariate stepwise regression analysis showed that individual-level factors (i.e., working experience length of geriatric nursing and attitudes toward caring for older adults), employer-level factors (i.e., departments, job responsibilities, the degree of satisfaction toward the attention and support and the promotion rules provided by the hospital or department), and training-associated factors (i.e., economic zone where training organizations are located and the degree to which the training content met clinical needs) are independently associated with gerontological nurse specialists' core competency level (P < 0.05). CONCLUSIONS: This study showed that gerontological nurse specialists' core competency needs further improvements, especially regarding professional development skills and research and analysis decision-making skills. Additionally, individual-, training-, and employer-level factors could influence their core competency level, indicating that interventions targeting these factors could be applied to improve the core competency of gerontological nurse specialists.

Cultural Influence on Nurses' Pain Observations Related to Dementia: An Integrative Review.

BACKGROUND: Nurses play a pivotal role in pain observation in people living with dementia. However, currently, there is little understanding of the influence culture may have on the way nurses observe pain experienced by people living with dementia. AIM: This review explores the influence of culture on nurses... pain observations experienced by people living with dementia. SETTINGS: Studies were included regardless of the setting (e.g., acute medical care, long-term care, community). DESIGN: An integrative review. PARTICIPANTS/SUBJECTS: PubMed, Medline, Psychological Information Database, Cochrane Library, Scopus, Web of Science, Cumulative Index of Nursing and Allied Health Literature, and ProQuest were included in the search. METHODS: Electronic databases were searched using synonyms for "dementia," "nurse," "culture," and "pain observation." The review included ten primary research papers following the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. RESULTS: Nurses reported that pain observation in people living with dementia is challenging. Four themes were identified by data synthesis: (1) using behaviors for pain observation; (2) information from carers for pain observation; (3) pain assessment tools for pain observation; and (4) role of knowledge, experience, and intuition in pain observation. CONCLUSIONS: There is a limited understanding of the role of culture on nurses' pain observations. However, nurses take a multifaceted approach to observing pain using behaviors, information from carers, pain assessment tools, and their knowledge, experience, and intuition.

Implementing PainChek and PARO to Support Pain Assessment and Management in Residents with Dementia: A Qualitative Study.

BACKGROUND: Pain is a common problem but often undiagnosed and untreated in people with dementia. AIMS: This study explored the experiences of residents with dementia, family, andformal carers with (1) pain assessment and management for residents with dementia; (2) the use of the PainChek app for pain assessment, and (3) the use of a social robot PARO for pain management in residents with dementia. DESIGN: A qualitative study. SETTINGS/PARTICIPANTS: Interviews were conducted with 13 residents withdementia, three family members, and 18 formal carers from a residential aged carefacility. METHOD: Residents with dementia interacted with PARO for 15 mins, five days perweek for three weeks. The PainChek app assessed pain levels before and after eachsession. After three-week intervention, individual interviews were conducted withresidents, family, and formal carers who experienced or observed the use of PainChekapp and PARO for residents. Interviews were audio-recorded, transcribed, andanalyzed using thematic analysis. RESULTS: Four themes were identified regarding pain in residents with dementia: (1) the impact, challenges and strategies of pain assessment and management; (2) benefits and barriers of using PainChek app to assess pain; (3) benefits of interacting with PARO to manage pain and behavioral symptoms; and (4) implementing PainChek app and PARO to support pain assessment and management in dementia care. CONCLUSIONS: Technology, such as PainChek and PARO, is promising to improve painassessment and reduce pain for people with dementia. Barriers to using technologyinclude limited staff training and the implementation of person-centered care.

Non-pharmacological interventions for older adults with postprandial hypotension: A scoping review.

BACKGROUND: Older adults frequently suffer from postprandial hypotension, associated with an increased risk of falls, syncope, acute cardiovascular and cerebrovascular diseases, and even death. Researchers use non-pharmacological interventions, but related literature is dispersed and lacks a latest summary. OBJECTIVE: The aim of this study was to map and examine non-pharmacological interventions currently employed to assist older adults with postprandial hypotension and lay a solid foundation for future studies. METHODS: This study adhered to the JBI methodology for scoping reviews and preferred reporting items for systematic reviews and meta-analyses extension for scoping reviews. PubMed, Web of Science, Embase, Cochrane Library, CINAHL, SCOPUS, Chinese Biomedical Journal, China National Knowledge Infrastructure, VIP and WAN FANG Data were retrieved from their inception to 1 August 2022. RESULTS: Two randomized controlled trials and seven quasi-experimental studies were included. Small meals, exercise interventions, fibre with meals, green tea and water therapy have been reported to prevent postprandial hypotension effectively; however, position changes have been reported to have no impact on postprandial blood pressure decrease. Additionally, the blood pressure determination methods and test meals may affect observed trial effects. CONCLUSION: Large samples and long-term follow-up studies are needed to prove the efficacy and safety of existing non-pharmacological interventions. Future studies should develop a BP determination method based on the postprandial BP decline trajectory induced by a given test meal to improve the reliability of study results. RELEVANCE TO CLINICAL PRACTICE: This review broadly summarizes existing studies on developing and validating non-pharmacological interventions for older adults with postprandial hypotension. It also analyses special factors that may influence the trial effects. This may provide a useful reference for future research.

Family Involvement in Pain Management for People Living With Dementia: An Integrative Review.

This review aimed to synthesize current evidence on family involvement in pain management for people living with dementia from the perceptions of family carers and health care professionals. An integrative review was conducted using CINAHL, Embase, PubMed, PsycINFO and Cochrane Library electronic databases. The Mixed Methods Appraisal Tool was used to appraise the articles, followed by thematic analysis. Twelve studies were included and four themes were identified: (1) The roles and responsibilities of family carers; (2) Enablers and barriers for pain identification; (3) Strategies and concerns for pain management; and (4) Lack of staff education and communication with health care providers. Family carers play an important role in pain assessment and management for people living with dementia, but they cannot be actively involved in this process due to a lack of communication with health care providers. An integrated approach that includes education and communication with family carers and health care providers is needed.

Feasibility study protocol of the PainChek app to assess the efficacy of a social robot intervention for people with dementia.

AIM: This study aims to test the feasibility of the PainChek app to assess pain for people with dementia living in residential aged care facilities (RACFs). It will also identify the optimal dosage and efficacy of a social robot (personal assistant robot [PARO]) intervention on chronic pain for people with dementia. DESIGN: This is a feasibility randomized controlled trial with three groups. METHODS: Forty-five residents living with dementia and chronic pain will be recruited from one RACF. The intervention consists of an individual 15-min non-facilitated session with a PARO robot twice a day (Group 1), a PARO robot once a day (Group 2), or a Plush-Toy (non-robotic PARO) once a day (Group 3) from Monday to Friday for 4 weeks. Participants will be followed at 4 and 8 weeks after baseline assessments. The primary outcome will be the feasibility of using the PainChek app to measure changes in pain levels before and after each session. Secondary outcomes include staff-rated pain levels, neuropsychiatric symptoms, quality of life and changes in psychotropic and analgesic medication use. Participants, staff and family perceptions of using PARO and the PainChek app will be collected after the 4-week intervention. DISCUSSION: This study will test the use of the PainChek app and PARO to improve pain management for people with dementia. Results from this study will help determine its usefulness, feasibility and acceptability for pain management in people with dementia living in RACFs. IMPACT: As pain is a significant problem for people with dementia, this project will generate evidence on the use of the PainChek to measure the efficacy of a social robot intervention that has the potential to improve the quality of pain care in people with dementia. TRIAL REGISTRATION: Australian and New Zealand Clinical Trials Registry number (ACTRN12621000837820) date registered 30/06/2021.

Restraint use in residents with dementia living in residential aged care facilities: A scoping review.

AIMS AND OBJECTIVES: To provide an overview of restraint use in residents with dementia in the context of residential aged care facilities. BACKGROUND: Restraints are commonly used in people with dementia living in residential aged care facilities to manage behaviours and reduce injuries, but the concept of restraint use in people with dementia remains ambiguous, and current practices to reduce restraint use in long-term care residents with dementia remain unclear. DESIGN: A scoping review using the methodological frameworks of Arskey and O'Malley and colleagues. METHODS: Nine databases (CINAHL, MEDLINE, EMBASE, PubMed, Scopus, Web of Science, OVID, Cochrane Central Register of Controlled Trials and ProQuest) were searched from 2005 to 20 May 2019. Articles were included if they were written in English, peer-reviewed and used any research method that described restraint use in residents with dementia living in residential care settings. The PRISMA-ScR checklist was used. RESULTS: From 1,585 articles, 23 met the inclusion criteria. There is a lack of a clear definition of restraint use, and the prevalence of restraint use varied from 30.7% to 64.8% depending on the different operational concepts. People with dementia were at a higher risk for restraint use, and the decision-making process for restraint use was largely ignored in the literature. The effect of staff educational interventions to reduce restraint use was inconsistent due to varying delivery duration and content. CONCLUSIONS: The prevalence of restraint use in people with dementia living in residential care settings remains high alongside the absence of a clear definition of restraint use. More research about the decision-making process involved in using restraint and development of effective interventions are needed. RELEVANCE TO CLINICAL PRACTICE: Better education about the decision-making regarding staff, conditions of residents and organisations for restraint use is needed to improve the care for people with dementia living in care settings.

How Did the COVID-19 Restrictions Impact People Living With Dementia and Their Informal Carers Within Community and Residential Aged Care Settings in Australia? A Qualitative Study.

The aim of this study was to explore how formal social support changed after implementation of the COVID-19 public health measures and how these restrictions affected people living with dementia and their informal carers in Australia. Sixteen informal carers and two people living with dementia were interviewed between August and November 2020. Participants were asked about their experiences of the pandemic and the impact that the restrictions had on their lives and care. Thematic analysis identified four overarching themes describing (a) prepandemic limitations of the aged care system, (b) the aged care system's response to the COVID-19 restrictions, (c) changes affecting informal carers, and (d) the challenges faced by people living with dementia. The findings highlighted the challenges faced by the Australian aged care system before the pandemic and the additional burden placed on informal carers who supported people living with dementia across residential and home settings during the pandemic.

Portable EEG monitoring for older adults with dementia and chronic pain - A feasibility study.

Given the reduced ability of people with dementia to self-report pain, this study examined the feasibility of using a portable electroencephalography (EEG) headband (MUSE 2) as a pain measurement tool for long-term care residents with dementia. Ten minutes of resting-state EEG was acquired by MUSE 2 from people with dementia experiencing ongoing pain (n = 3) and without current pain (n = 1) over three days. The MUSE 2 was acceptable and feasible for use in people with dementia while challenges regarding software, data collection and analysis in using this device are reported. Compared to the resident not experiencing pain, EEG signals of residents with ongoing pain showed different EEG patterns, and this could be a potential biomarker to support pain measurement in people with dementia. Further research with larger sample size is warranted to verify study results.

Effects of propofol on intracranial pressure and prognosis in patients with severe brain diseases undergoing endotracheal suctioning.

BACKGROUND: To investigate whether the administration of intravenous propofol before endotracheal suctioning (ES) in patients with severe brain disease can reduce the sputum suction response, improve prognosis, and accelerate recovery. METHODS: A total of 208 severe brain disease patients after craniocerebral surgery were enrolled in the study. The subjects were randomly assigned to the experimental group (n = 104) and the control group (n = 104). The experimental group was given intravenous propofol (10 ml propofol with 1 ml 2% lidocaine), 0.5-1 mg/kg, before ES, while the control group was subjected to ES only. Changes in vital signs, sputum suction effect, the fluctuation range of intracranial pressure (ICP) before and after ES, choking cough response, short-term complications, length of stay, and hospitalization cost were evaluated. Additionally, the Glasgow Outcome Scale (GOS) prognosis score was obtained at 6 months after the operation. RESULTS: At the baseline, the characteristics of the two groups were comparable (P > 0.05). The increase of systolic blood pressure after ES was higher in the control group than in the experimental group (P < 0.05). The average peak value of ICP in the experimental group during the suctioning (15.57 ± 12.31 mmHg) was lower than in the control group (18.24 ± 8.99 mmHg; P < 0.05). The percentage of patients experiencing cough reaction- during suctioning in the experimental group was lower than in the control group (P < 0.05), and the fluctuation range of ICP was increased (P < 0.0001). The effect of ES was achieved in both groups. The incidence of short-term complications in the two groups was comparable (P > 0.05). At 6 months after the surgery, the GOS scores were significantly higher in the experimental than in the control group (4-5 points, 51.54% vs. 32.64%; 1-3 points, 48.46% vs. 67.36%; P < 0.05). There was no significant difference in the length of stay and hospitalization cost between the two groups. CONCLUSIONS: Propofol sedation before ES could reduce choking cough response and intracranial hypertension response. The use of propofol was safe and improved the long-term prognosis. The study was registered in the Chinese Clinical Trial Registry on May 16, 2015 (ChiCTR-IOR-15006441).

How people with dementia perceive a therapeutic robot called PARO in relation to their pain and mood: A qualitative study.

BACKGROUND: Interacting with social robots, such as the robotic seal PARO, has been shown to improve mood and acute pain for people with dementia. Little attention has been paid to the effect of PARO on people with dementia and chronic pain. OBJECTIVE: To explore how people with mild to moderate dementia and chronic pain perceive PARO as an alternative intervention to manage their pain and mood. DESIGN: A descriptive qualitative approach nested within a pilot randomised controlled trial. METHODS: Participants with dementia and chronic pain were recruited from three residential aged care facilities. They interacted with PARO for 30 min, 5 days a week over a 6-week period. A sample of 11 participants completed individual semi-structured interviews at the end of the intervention. Data were collected from January 2018-January 2019. Inductive thematic analysis was undertaken. Reporting of findings followed the COREQ checklist. RESULTS: Four themes emerged from the data: (a) perceptions of PARO; (b) therapeutic effects of PARO; (c) limitations of PARO; and (d) programme improvement. Residents with dementia expressed positive attitudes towards the use of PARO and acknowledged the therapeutic benefits of PARO on mood improvement and relaxation for pain relief but also mentioned the limitations of its weight, voice and characteristics. Residents' responses could also fluctuate during the intervention process, and individual preferences need to be considered. CONCLUSIONS: The PARO intervention is a promising intervention to improve positive emotion, and there is some anecdotal evidence that pain may be decreased from the perspectives of people living with chronic pain and dementia. RELEVANCE TO CLINICAL PRACTICE: Long-term care staff may incorporate PARO therapy into daily dementia care. Understanding of individual's preferences may enhance the implementation of PARO for pain management in this group.

The effectiveness of nurse-led interventions for preventing urinary tract infections in older adults in residential aged care facilities: A systematic review.

AIMS AND OBJECTIVES: To explore the effectiveness of nurse-led interventions to prevent urinary tract infections in older adults living in residential aged care facilities. BACKGROUND: While most empirical studies focus on the treatment of urinary tract infections, few studies have examined the effectiveness of nurse-led interventions in preventing urinary tract infections. DESIGN: Systematic review. METHODS: Eight electronic databases were searched for relevant studies published between 2008-2018. The inclusion criteria were as follows: (a) a focus on older adults, (b) evaluation of nurse-led interventions, focusing on prevention of urinary tract infection, (c) implemented in residential aged care facilities, and (d) outcomes reported as incidence or prevalence of urinary tract infection. The selected papers were critically appraised using the Mixed Methods Appraisal Tool. The data were analysed with narrative synthesis, and findings were reported following the PRISMA guidelines. RESULTS: A review of 1,614 titles and abstracts identified four studies that met the inclusion criteria. Three types of nurse-led interventions were identified: (a) the appointment of advanced practice nurses, (b) those focused on a single specific nursing intervention, and (c) implementation of a multicomponent nursing intervention. All included studies reported at least some positive outcomes. However, the included studies were highly heterogeneous and it was impossible to determine the most effective intervention approach. CONCLUSIONS: Nurses are leaders in health care and are well placed to lead prevention of urinary tract infections in residential aged care; however, evidence of the effectiveness of a nurse-led approach is limited. High-quality randomised controlled trials are warranted to address the knowledge gap and advance practice in this area. RELEVANCE TO CLINICAL PRACTICE: When developing an effective nurse-led intervention programme, the programme should be grounded in nurse-led principles and consider the complex staffing factors to ensure that nurse-led programmes are tailored to an effective level.

Psychosocial interventions for pain management in older adults with dementia: A systematic review of randomized controlled trials.

AIM: To assess the effectiveness of psychosocial interventions on pain in older adults living with dementia. DESIGN: A systematic review with meta-analysis of randomized controlled trials. DATA SOURCES: Scopus, ProQuest, EBSCO (CINAHL and MEDLINE), PubMed, OVID (PsycINFO), Web of Science, and Cochrane Library were searched from their inception up to 2 May 2018. REVIEW METHODS: Risk of bias assessment and meta-analysis were conducted according to the Cochrane methods using RevMan 5.3 and findings were generated using the GRADE profiler software. RESULTS: Eight studies met the inclusion criteria, but the quality of the current evidence was low to moderate. Results showed that psychosocial interventions significantly reduced the observational pain score and pain medication. Subgroup analyses indicated that sensory stimulation and individual interventions showed a reduction in observational pain in people with dementia. CONCLUSION: Findings suggest that psychosocial interventions may be potentially effective alternatives for pain management in people with dementia. However, caution is needed in interpreting these results due to limited studies, risk of bias and heterogeneity across studies. Furthermore, well-designed research is needed on psychosocial interventions to strengthen quality of pain management in people with dementia. IMPACT: This review synthesized current evidence using psychosocial interventions to manage pain in people with dementia. Findings suggest that psychosocial interventions may lead to a potential reduction in pain and pain medication in people with dementia. Healthcare providers may wish to integrate psychosocial interventions as part of the multimodal approach to the management of pain in people living with dementia.

Hypoxia-Inducible Factor-1α Gene Expression and Apoptosis in Ischemia-Reperfusion Injury: A Rat Model of Early-Stage Pressure Ulcer.

BACKGROUND: Pressure ulcer (PU) is a significant and complicated health problem. Although ischemia-reperfusion (I/R) injury has been identified as the primary mechanism in the early stage of pressure ulceration, the cellular and molecular events contributing to I/R injury of PU development are unclear. OBJECTIVES: The aim of this study was to characterize hypoxia-inducible factor-1α (HIF-1α) expression profile and elaborate the apoptotic pathways based on an I/R injury model of PU in rats. METHODS: Two related experiments were conducted. The purpose of Experiment 1 was to establish an animal model of early-stage PU (Stage I PU). Forty-eight rats were randomly divided into six groups of eight. Each group received three cycles of I/R, but with different magnitudes of pressure-which ranged from 100 to 270 mm Hg-except for Control Group A. On the basis of this established animal model, Experiment 2 focused on the I/R mechanism of early-stage PU. The 36 rats used in Experiment 2 were randomly divided into one control and two experimental groups; the experimental groups received the same magnitude of pressure (170 mm Hg), but either 3 or 5 I/R cycles. Tissue underneath the compressed region, including the skin and muscle tissue, was incised for immunohistochemistry, enzyme-linked immunosorbent assay, TdT-mediated dUTP nick-end labeling, and real-time polymerase chain reaction gene expression analysis. RESULTS: HIF-1α gene expression in the compressed muscle tissue was slightly reduced in the 3 I/R group, but significantly elevated in the 5 I/R group (p < .05). The compressed tissue showed inflammation and evidence of oxidative stress reaction. ATPase activity was lower when cycles of I/R were prolonged. TdT-mediated dUTP nick-end labeling analysis showed a significant increase in the compressed muscle tissue relative to the control. Bax and Bcl-2 proteins expressed reversely. DISCUSSION: These results suggest that mitochondria-mediated apoptotic pathways may be involved in the development of early-stage PU, and HIF-1α might play a potential role for promoting apoptosis. Inflammation, oxidative stress reaction, and energy depletion may cooperate in the process of I/R injury of early-stage PU.
